EXPIRED For Sale Balanced Audio Technology VK5 Pre Amplifier

Further Information

BAT (Balanced Audio Technology) VK 5 Balanced Line Preamplifier in excellent condition with a spare set of tubes.

Also included:  CARDAS Balanced to Single Ended & Single Ended to Balanced adaptors for interfacing to single ended only equipment.

                            Neotec power cable.

                            Black Diamond Racing Pucks and Cones isolation feet.

The VK-5 is very quiet and a true all-tube, fully balanced Class A differential design with no solid-state devices in the signal path.

Power regulation is implemented by tubes, rather than the less satisfying solid-state regulation found in modern designs.

Additionally, the unit is a dual mono design with zero feedback.

Its build quality is superb. It is an early BAT model and is in my opinion better in quality than current BATs.

There is lots on the web so you can do research.

Great value for money. Class A Recommended Component by "STEREOPHILE" Magazine:

"Excuse me, how do I get to Carnegie Hall?" goes the setup for the old joke. The punchline is, of course, "Practice." For anyone who wants to get into high-end audio design and manufacturing, desire and talent are not enough. Those who succeed in this highly competitive area really have to do their homework—which is just what Balanced Audio Technology has done. Starting with theoretical analysis of design alternatives, through extensive measurements and listening, they've produced a pair of audio components that, in my opinion, are in the front rank of their respective categories. For a company that no one had heard of a year ago, this is a remarkable accomplishment.

The VK-5 retains the transparency of a minimalist line-stage, but has enough facilities that make it convenient to use. The VK-60 offers the natural rendition of instrumental/vocal timbres that the best tube amplifiers are known for, but has enough power to drive most speakers to very satisfying volumes, especially when used in the monoblock configuration. In balanced or unbalanced mode, used together or with other high-quality amplifiers/preamps, the VK-5 and the VK-60 performed in a way that was always musical and true to the spirit of high fidelity.
